find the volumes of the following objects cones height= x cm radius = 2x cm​

1 thought on “find the volumes of the following objects cones height= x cm radius = 2x cm​”

1. Answer:

   Volume = [tex]\frac{88x^{3} }{21} cm^{3}[/tex]

   Step-by-step explanation:

   Volume of cone = [tex]\frac{1}{3}[/tex] π [tex]r^{2} h[/tex]

   Given : r = 2x cm , h = x cm

   ⇒ Volume of cone = [tex]\frac{1}{3} (\frac{22}{7} )((2x)^{2})(x)[/tex] = [tex]\frac{88x^{3} }{21} cm^{3}[/tex]
